So far I likes what I sees.
First off..This thing came all the way from China to Charlotte, NC in 2 days. I got a shipping notice on the Jan 19th and Here it is on the 20th.
I have never really used OSX, except looking at it in the store. It is nicley done. In some ways Linux with Gnome is like it, but OSX, of course is more polished and the interface is a little different.
Garageband is very easy to use, I was throwing together music in no time. I am hoping that the rest of iLife will be the same and I think that it will be.
